autochanging of control

[Sergey Yakovlev]

Hello, All!
Is it possible in LabVIEW 6 - to make a control picture changing when mouse
pointer placed over it?

You can use Win API functions to get position of mouse pointer. Few days ago here was an answer with description where you can get Win API toolkit for LV. But in any case you can use windows DLLs to do it (User32.dll void GetCursorPos(POINT FAR* lppt)).
Then you have to get the positions of your picture control with the help of its Property Node and check if the pointer is inside this region.

??!
This way is known and good when you have a small amount of controls and all
controls are fixed in positions on panel. My task is more complicated and
I'd like to find more intelligent solution.

May be most inteligent is LabVindows/CVI with libraty Run-Time Moveble
control and all UI
indeed.

Yakovlev;

There is a work-around to do that by using a picture control. The picture control has a property for mouse position.

In LabVIEW's Help, check the example "Mouse Control" located in "Picture Control Examples". There is also an example in Developer's Zone:

Using the Picture Indicator to Assign Mouse Events to a Front Panel Object
